i l Letters Patent No. 66,155, dated June 25, 1867.

GANG-PLOUGH.

TO-ALL WHOM IT MAY CONCERN: Y

, Be itknown that I, JOHN T. LEGG, of the county of Lewis, in the State of Missouri, have invented a new and useful improvement in Gang-Ploughs; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, referenceA being had to-the annexed drawings, lmaking a part of this specification, in Which i Figure 1 is a perspective view, and i Figure 2 a birds-eye view.

Figure 3 is a representation of the lever used to 'raise the front part of t'he beams; and

Figure 4 represents the same lever as it appears from viewing it in the direction of the tongue.

4.A A represent the ploughs' made in form same as thosein common use, and are attached to the. beams ,by 4the braces B B', made securely fast to the land-boards ofthe ploughs; also by the braces C C', attached to the foot ofthe landLboards, and by the braces D D attached-to the ears of the mouldboa`rds. E E are the beams, sustained by the leverV attachments, as hereinafter described. F F are rods linked in the loops of the bolts extending through lthe beams, as show n in the drawings; at the other end they are linked into the rings of the levers termini. Gr G are rods extending fromfthesame termini to staples in the ears of the ploughs. H I'I are compound levers with fulcra at II', in the beam-stays, which extend above the carriage forthis purpose.

'These levers are operated by the handles K4 K', which, in turn, are fastened to the carriage of the plough at LL. The object of this combination is to enable the attendant to raise the heels ofthe ploughs at s'uch height as he may desire; either one or-both may be raised at his option. M M are ratchets in which the levers work. At thelower ends of the lever-handles are attached springs, which press them in the ratchets, holding `them in .such positions asmay be required. N N are levers made in the forms shown iniigs. 3 land. 4, operating in the ratchets M M', but upon the opposite sidesl from the other levers, and are connected with the forward part of the beamsby links, as shown by the dotted lines in iig. 2. The object of these levers is to raise 0 1' lower the ploughs. The beams, at `this point, are conined in the steadying-postsiO O, corresponding to those at the rear of the carriage.` The forward braces are fastened upon the axle of the carriage, and strengthened by additional braces on the outside posts, and also between the inside ones, I Y are stay-chains fixed upon the axle Y of the carriage-by staple or otherwise-and one end of them made fast to the'rear part of the beams, and the otherV one fast in the bolt extending through the tongue-staples on the ends of the beams. Q is the team-tongue, having the-universal joint connpctingl it with the beams of the ploughs. At R is an iron strap, intended to receive the end of the stiii'ening-pole. S is the stiening or guiding-pole, fastened to the axle of the carriage by abolt extendingrthrough it, and also by the bolt in the front cross-piece ofthe frame of the carriage. The objectof this pole is to guide themachline, and also to lessen the weight of the tongue` upon the horses necks,

-when one of the ploughs, or both, are raised-out of the ground.

` The carriage of the plough consists of two pieces of timber, corresponding in length to the beams of the ploughs. These pieces are fastened tothe axle of the machine by bolts, and are also attached to each other byV cross-ties. Upon the front of the axle are fastened the steadyingposts for the fore .part of the beams; and at the rear ends of the lengthwise pieces of the frame are posts of the same character, the ends of which extend .through the pieces and form the rests` for the levers'heretoi'ore described.

The axle of the machine is broken at the furrow-wheel, and spliced by placing a piece under the same, of

sufficient depth or size as to bring the machine upon a level when the wheel is in the furrow.

The ploughs, as shown inthe drawings, do not come as far back as 'it is designed to make them in the practical machine; in it,'it is designed to make the point of the share of the righhand plough come behind the wheel, and the other acorresponding distance back.

What I claim as my improvement, and desire to secure by Letters Patent, is'

1. The ploughs A A, beams E E, rods F F and Gr G', fthe compound levers H H', lever-handles K K, and ratchets M M', arranged, combined, and operating for the purpose and in the manner substantially as described. l v

2. I claim the levers N N and ratchet M M, arranged, combined, and operating for the purpose and in the manner described. Y A l 3. I claim the stay-chains P P,'they beams'E E', the tongue Q, the strap R, and the stiii'ening-pole S, arranged, combined, and operating in the manner and for the purpose described. Y
